Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles. The consolidated financial statements and the footnotes of First Guaranty Bancshares, Inc. ("First Guaranty") thereto should be read in conjunction with the audited consolidated financial statements and note disclosures for First Guaranty previously filed with the Securities and Exchange Commission in First Guaranty's Annual Report on Form 10-K for the year ended December 31, 2020. The consolidated financial statements include the accounts of First Guaranty Bancshares, Inc. and its wholly owned subsidiary First Guaranty Bank (the "Bank"). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of the consolidated financial statements. Those adjustments are of a normal recurring nature. The results of operations at March 31, 2021 and for the three month periods ended March 31, 2021 and 2020 are not necessarily indicative of the results expected for the full year or any other interim period. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, and the valuation of investment securities.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting PronouncementsIn June 2016, the FASB issued ASU 2016-13, "Financial Instruments- Credit Losses: Measurement of Credit Losses on Financial Instruments". This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. The ASU amendments require the measurement of all expected credit losses for financial assets held at the reporting date be based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires assets held at cost basis to reflect the company's current estimate of all expected credit losses. For available for sale debt securities, credit losses should be presented as an allowance rather than as a write-down. In addition, this ASU amends the accounting for purchased financial assets with credit deterioration. On October 16, 2019, the FASB approved an effective date delay applicable to smaller reporting companies until fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. First Guaranty is a smaller reporting company and has delayed the adoption of ASU 2016-13.

This was done following the review of guidance for held to maturity portfolios in light of the COVID-19 pandemic. First Guaranty had terminated its held to maturity portfolio in the first quarter of 2020 due to the economic conditions associated with COVID-19. ASC 320-10-25 provides an exemption for events that are isolated, nonrecurring, and unusual for the reporting entity. The termination of the held to maturity portfolio in the first quarter of 2020 did not taint the portfolio under this guidance. The securities designated as held to maturity are agency securities that are part of First Guaranty’s investment strategy and public funds collateralization program. The scheduled maturities of securities at March 31, 2021, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities due to calls or prepayments. Mortgage-backed securities are not due at a single maturity because of amortization and potential prepayment of the underlying mortgages. For this reason they are presented separately in the maturity table below: At March 31, 2021 (in thousands) Amortized Cost Fair Value Available for sale: Due in one year or less $ 5,217 $ 5,227 Due after one year through five years 4,514 4,552 Due after five years through 10 years 44,127 44,445 Over 10 years 12,193 12,457 Subtotal 66,051 66,681 Mortgage-backed securities 991 1,011 Total available for sale securities $ 67,042 $ 67,692 Held to maturity: Due in one year or less $ — $ — Due after one year through five years — — Due after five years through 10 years 19,343 18,777 Over 10 years 133,583 129,383 Total held to maturity securities $ 152,926 $ 148,160 At March 31, 2021, $171.4 million of First Guaranty's securities were pledged to secure public funds deposits and borrowings.

The 10 securities had an aggregate amortized cost basis of $1.6 million and an unrealized loss of $0.1 million at March 31, 2021. Management has the intent and ability to hold these debt securities until maturity or until anticipated recovery. Securities are evaluated for other-than-temporary impairment at least quarterly and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) the recovery of contractual principal and interest and (iv) the intent and ability of First Guaranty to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Investment securities issued by the U.S. Government and Government sponsored enterprises with unrealized losses and the amount of unrealized losses on those investment securities that are the result of changes in market interest rates will not be other-than-temporarily impaired. First Guaranty has the ability and intent to hold these securities until recovery, which may not be until maturity. Corporate debt securities in a loss position consist primarily of corporate bonds issued by businesses in the financial, insurance, utility, manufacturing, industrial, consumer products and oil and gas industries. There were no securities with an other-than-temporary impairment loss at March 31, 2021. First Guaranty believes that the remaining issuers will be able to fulfill the obligations of these securities based on evaluations described above. First Guaranty has the ability and intent to hold these securities until they recover, which could be at their maturity dates. There were no other-than-temporary impairment losses recognized on securities during the three months ended March 31, 2021 and 2020. The following table presents a roll-forward of the amount of credit losses on debt securities held by First Guaranty for which a portion of OTTI was recognized in other comprehensive income for the three months ended March 31, 2021 and 2020: (in thousands) Three Months Ended Three Months Ended Beginning balance of credit losses at end of prior year $ 100 $ — Other-than-temporary impairment credit losses on securities not previously OTTI — — Increases for additional credit losses on securities previously determined to be OTTI — — Reduction for increases in cash flows — — Reduction due to credit impaired securities sold or fully settled (100) — Ending balance of cumulative credit losses recognized in earnings at end of period $ — $ — In the first three months of 2021 there were no other-than-temporary impairment credit losses on securities for which we had previously recognized OTTI. For securities that have indications of credit related impairment, management analyzes future expected cash flows to determine if any credit related impairment is evident. Estimated cash flows are determined using management's best estimate of future cash flows based on specific assumptions. The assumptions used to determine the cash flows were based on estimates of loss severity and credit default probabilities. Management reviews reports from credit rating agencies and public filings of issuers. At March 31, 2021, First Guaranty's exposure to bond issuers that exceeded 10% of shareholders' equity is below: At March 31, 2021 (in thousands) Amortized Cost Fair Value Federal Home Loan Mortgage Corporation (Freddie Mac-FHLMC) 105,221 101,835 Federal Farm Credit Bank (FFCB) 52,102 50,509 Total $ 157,323 $ 152,344

The carrying amount of those loans is as follows at March 31, 2021 and December 31, 2020.

Where First Guaranty can reasonably estimate the cash flows expected to be collected on the loans, a portion of the purchase discount is allocated to an accretable yield adjustment based upon the present value of the future estimated cash flows versus the current carrying value of the loan and the accretable yield portion is being recognized as interest income over the remaining life of the loan. Where First Guaranty cannot reasonably estimate the cash flows expected to be collected on the loans, it has decided to account for those loans using the cost recovery method of income recognition. As such, no portion of a purchase discount adjustment has been determined to meet the definition of an accretable yield adjustment on those loans accounted for using the cost recovery method. If, in the future, cash flows from the borrower(s) can be reasonably estimated, a portion of the purchase discount would be allocated to an accretable yield adjustment based upon the present value of the future estimated cash flows versus the current carrying value of the loan and the accretable yield portion would be recognized as interest income over the remaining life of the loan. Until such accretable yield can be calculated, under the cost recovery method of income recognition, all payments will be used to reduce the carrying value of the loan and no income will be recognized on the loan until the carrying value is reduced to zero. The accretable yield, or income expected to be collected, on the purchased loans above is as follows for the three months ended March 31, 2021 and 2020.

Payment status, collateral value and the probability of collecting scheduled principal and interest payments when due are considered in evaluating loan impairment.

The modifications to First Guaranty's TDRs are generally concessions on either the interest rate charged or the amortization. The effect of the modifications to First Guaranty would be a reduction in interest income. First Guaranty has not restructured any loans that are considered TDRs in the three months ended March 31, 2021. At March 31, 2021 First Guaranty had one outstanding TDR. Under section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which was signed into law on March 27, 2020 and as amended by subsequent legislation, financial institutions have the option to temporarily suspend certain requirements under U.S. generally accepted accounting principles related to troubled debt restructurings for a limited period of time to account for the effects of COVID-19. This provision allows a financial institution the option to not apply the guidance on accounting for troubled debt restructurings to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) January 1, 2022 or (ii) 60 days after the end of the COVID-19 national emergency.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and intangible assets deemed to have indefinite lives are no longer amortized, but are subject to impairment testing. Other intangible assets continue to be amortized over their useful lives. First Guaranty's goodwill is the difference in purchase price over the fair value of net assets acquired from its acquisition of Homestead Bancorp in 2007, Premier Bancshares, Inc. in 2017 and Union Bancshares, Incorporated in 2019. Goodwill totaled $12.9 million at March 31, 2021 and December 31, 2020. No impairment charges have been recognized on First Guaranty's intangible assets since acquisition. Loan servicing assets decreased $43,000 to $0.7 million at March 31, 2021 compared to $0.8 million in December 31, 2020. Other intangible assets recorded include core deposit intangibles, which are subject to amortization. The weighted-average amortization period remaining for First Guaranty's core deposit intangibles is 8 years at March 31, 2021. The core deposits intangible reflect the value of deposit relationships, including the beneficial rates, which arose from acquisitions. In accordance with ASC Topic 350, Intangibles - Goodwill and Other, during the first quarter of 2021, we evaluated recent potential triggering events that might be indicators that our goodwill was impaired. The events include, among others, the economic disruption and uncertainty surrounding the COVID-19 pandemic and the significant decline in our stock price. Based on our evaluation, we concluded that our goodwill was not impaired as of March 31, 2021.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-balance sheet commitments First Guaranty is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby and commercial letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of the involvement in particular classes of financial instruments. The exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby and commercial letters of credit is represented by the contractual notional amount of those instruments. The same credit policies are used in making commitments and conditional obligations as it does for balance sheet instruments. Unless otherwise noted, collateral or other security is not required to support financial instruments with credit risk. Below is a summary of the notional amounts of the financial instruments with off-balance sheet risk at March 31, 2021 and December 31, 2020: Contract Amount (in thousands) March 31, 2021 December 31, 2020 Commitments to Extend Credit $ 157,545 $ 154,047 Unfunded Commitments under lines of credit $ 199,322 $ 169,151 Commercial and Standby letters of credit $ 11,719 $ 11,728 Litigation The nature of First Guaranty's business ordinarily results in a certain amount of claims, litigation and legal and administrative cases, all of which are considered incidental to the normal conduct of business. When First Guaranty determines it has defenses to the claims asserted, it defends itself. First Guaranty will consider settlement of cases when it is in the best interests of both First Guaranty and its shareholders. While the final outcome of legal proceedings is inherently uncertain, based on information currently available as of March 31, 2021, any incremental liability arising from First Guaranty's legal proceedings in excess of any liability accrued will not have a material adverse effect on First Guaranty's financial position or results of operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value of a financial instrument is the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Valuation techniques use certain inputs to arrive at fair value. Inputs to valuation techniques are the assumptions that market participants would use in pricing the asset or liability. They may be observable or unobservable. First Guaranty uses a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds or credit risks) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities available for sale. Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Securities classified within Level 3 in First Guaranty's portfolio as of March 31, 2021 includes corporate debt and municipal securities. Impaired loans. Loans are measured for impairment using the methods permitted by ASC Topic 310. Fair value of impaired loans is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Other real estate owned. Properties are recorded at the balance of the loan or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Fair values of other real estate owned ("OREO") are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values or recent sales activity for similar assets in the property's market; thus OREO measured at fair value would be classified within either Level 2 or Level 3 of the hierarchy. Certain non-financial assets and non-financial liabilities are measured at fair value on a non-recurring basis including assets and liabilities related to reporting units measured at fair value in the testing of goodwill impairment, as well as intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. The following table summarizes financial assets measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: (in thousands) March 31, 2021 December 31, 2020 Available for Sale Securities Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ 3,500 $ 3,000 Level 2: Significant Other Observable Inputs 47,700 209,359 Level 3: Significant Unobservable Inputs 16,492 26,189 Securities available for sale measured at fair value $ 67,692 $ 238,548 First Guaranty's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While the methodologies used are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value. The change in Level 1 securities available for sale from December 31, 2020 to March 31, 2021 was due to a net increase in Treasury bills of $0.5 million. The change in Level 2 securities available for sale from December 31, 2020 to March 31, 2021 was due principally to transfer of $152.9 million in U.S. Government agency securities from the available for sale to the held to maturity portfolio. $0.8 million in corporate securities and $1.1 million in municipal securities were transferred from Level 3 to Level 2 from December 31, 2020 to March 31, 2021. There were no transfers between Level 1 and 2 securities available for sale from December 31, 2020 to March 31, 2021. The following table reconciles assets measured at fair value on a recurring basis using unobservable inputs (Level 3) : Level 3 Changes (in thousands) March 31, 2021 Balance, beginning of year $ 26,189 Total gains or losses (realized/unrealized): Included in earnings — Included in other comprehensive income (228) Purchases, sales, issuances and settlements, net (7,625) Transfers in and/or out of Level 3 (1,844) Balance as of end of period $ 16,492 There were no gains or losses for the period included in earnings attributable to the change in unrealized gains or losses related to assets still held as of March 31, 2021.

The fair value option established by this statement permits First Guaranty to choose to measure eligible items at fair value at specified election dates and report unrealized gains and losses on items for which the fair value option has been elected in earnings at each reporting date subsequent to implementation. First Guaranty has chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with accounting principles generally accepted in the United States.

Financial Instruments, Owned, at Fair Value [Abstract]
Financial Instruments	Financial Instruments Fair value estimates are generally subjective in nature and are dependent upon a number of significant assumptions associated with each instrument or group of similar instruments, including estimates of discount rates, risks associated with specific financial instruments, estimates of future cash flows and relevant available market information. Fair value information is intended to represent an estimate of an amount at which a financial instrument could be exchanged in a current transaction between a willing buyer and seller engaging in an exchange transaction. However, since there are no established trading markets for a significant portion of First Guaranty's financial instruments, First Guaranty may not be able to immediately settle financial instruments; as such, the fair values are not necessarily indicative of the amounts that could be realized through immediate settlement. In addition, the majority of the financial instruments, such as loans and deposits, are held to maturity and are realized or paid according to the contractual agreement with the customer. Quoted market prices are used to estimate fair values when available. However, due to the nature of the financial instruments, in many instances quoted market prices are not available. Accordingly, estimated fair values have been estimated based on other valuation techniques, such as discounting estimated future cash flows using a rate commensurate with the risks involved or other acceptable methods. Fair values are estimated without regard to any premium or discount that may result from concentrations of ownership of financial instruments, possible income tax ramifications or estimated transaction costs. The fair value estimates are subjective in nature and involve matters of significant judgment and, therefore, cannot be determined with precision. Fair values are also estimated at a specific point in time and are based on interest rates and other assumptions at that date. As events change the assumptions underlying these estimates, the fair values of financial instruments will change. Disclosure of fair values is not required for certain items such as lease financing, investments accounted for under the equity method of accounting, obligations of pension and other postretirement benefits, premises and equipment, other real estate, prepaid expenses, the value of long-term relationships with depositors (core deposit intangibles) and other customer relationships, other intangible assets and income tax assets and liabilities. Fair value estimates are presented for existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses have not been considered in the estimates. Accordingly, the aggregate fair value amounts presented do not purport to represent and should not be considered representative of the underlying market or franchise value of First Guaranty. Because the standard permits many alternative calculation techniques and because numerous assumptions have been used to estimate the fair values, reasonable comparison of the fair value information with other financial institutions' fair value information cannot necessarily be made. The methods and assumptions used to estimate the fair values of financial instruments are as follows: Cash and due from banks, interest-bearing deposits with banks, federal funds sold and federal funds purchased. These items are generally short-term and the carrying amounts reported in the consolidated balance sheets are a reasonable estimation of the fair values. Investment Securities. Fair values are principally based on quoted market prices. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments or the use of discounted cash flow analyses. Loans Held for Sale. Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. These loans are classified within level 3 of the fair value hierarchy. Loans, net. Market values are computed present values using net present value formulas. The present value is the sum of the present value of all projected cash flows on an item at a specified discount rate. The discount rate is set as an appropriate rate index, plus or minus an appropriate spread. These loans are classified within level 3 of the fair value hierarchy. Impaired loans. Fair value of impaired loans is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Cash Surrender of BOLI. The cash surrender value of BOLI approximates fair value. Accrued interest receivable. The carrying amount of accrued interest receivable approximates its fair value. Deposits. The fair value of demand deposits, savings and interest-bearing demand deposits is the amount payable on demand. The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. Deposits are classified within level 3 of the fair value hierarchy. Accrued interest payable. The carrying amount of accrued interest payable approximates its fair value. Borrowings. The carrying amount of federal funds purchased and other short-term borrowings approximate their fair values. The fair value of First Guaranty's long-term borrowings is computed using net present value formulas. The present value is the sum of the present value of all projected cash flows on an item at a specified discount rate. The discount rate is set as an appropriate rate index, plus or minus an appropriate spread. Borrowings are classified within level 3 of the fair value hierarchy. Other Unrecognized Financial Instruments. The fair value of commitments to extend credit is estimated using the fees charged to enter into similar legally binding agreements, taking into account the remaining terms of the agreements and customers' credit ratings. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. Noninterest-bearing deposits are held at cost. The fair values of letters of credit are based on fees charged for similar agreements or on estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. At March 31, 2021 and December 31, 2020 the fair value of guarantees under commercial and standby letters of credit was not material. The carrying amounts and estimated fair values of financial instruments at March 31, 2021 were as follows: Fair Value Measurements at March 31, 2021 Using (in thousands) Carrying Amount Level 1 Level 2 Level 3 Total Assets Cash and due from banks $ 290,865 $ 290,865 $ — $ — $ 290,865 Federal funds sold 185 185 — — 185 Securities, available for sale 67,692 3,500 47,700 16,492 67,692 Securities, held for maturity 152,926 — 148,160 — 148,160 Loans held for sale — — — — — Loans, net 1,941,640 — — 1,956,778 1,956,778 Cash surrender value of BOLI 5,449 — — 5,449 5,449 Accrued interest receivable 13,393 — — 13,393 13,393 Liabilities Deposits $ 2,314,670 $ — $ — $ 2,326,198 2,326,198 Short-term advances from Federal Home Loan Bank — — — — — Repurchase agreements 6,205 — — 6,233 6,233 Accrued interest payable 4,471 — — 4,471 4,471 Long-term advances from Federal Home Loan Bank 3,327 — — 3,327 3,327 Senior long-term debt 40,844 — — 40,882 40,882 Junior subordinated debentures 14,787 — — 14,476 14,476 The carrying amounts and estimated fair values of financial instruments at December 31, 2020 were as follows: Fair Value Measurements at December 31, 2020 Using (in thousands) Carrying Amount Level 1 Level 2 Level 3 Total Assets Cash and due from banks $ 298,903 $ 298,903 $ — $ — $ 298,903 Federal funds sold 702 702 — — 702 Securities, available for sale 238,548 3,000 209,359 26,189 238,548 Securities, held for maturity — — — — — Loans, net 1,819,617 — — 1,846,738 1,846,738 Cash surrender value of BOLI 5,427 — — 5,427 5,427 Accrued interest receivable 11,933 — — 11,933 11,933 Liabilities Deposits $ 2,166,318 $ — $ — $ 2,179,004 2,179,004 Short-term advances from Federal Home Loan Bank 50,000 — — 50,000 50,000 Repurchase agreements 6,121 — — 6,154 6,154 Accrued interest payable 5,292 — — 5,292 5,292 Long-term advances from Federal Home Loan Bank 3,366 — — 3,366 3,366 Senior long-term debt 42,366 — — 42,408 42,408 Junior subordinated debentures 14,777 — — 14,452 14,452 There is no material difference between the contract amount and the estimated fair value of off-balance sheet items that are primarily comprised of short-term unfunded loan commitments that are generally at market prices.

Unusual or Infrequent Items, or Both [Abstract]
COVID-19	COVID-19 The COVID-19 pandemic has caused significant economic dislocation in the United States as many state and local governments, including in Louisiana and Texas, have ordered businesses and individuals to modify their normal practices. As of March 31, 2021, some of these restrictions have been removed and many non-essential businesses have been allowed to re-open in a limited capacity, adhering to social distancing and disinfection guidelines. However, these restrictions and other consequences have resulted in an unprecedented slow-down in economic activity and a related increase in unemployment. Since the COVID-19 pandemic began, millions of people have filed claims for unemployment, and the stock market has been volatile. Certain industries have been particularly adversely affected, including the travel and hospitality industry, the restaurant industry and the retail industry. Finally, the spread of the coronavirus has caused us to modify our business practices, including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences. As of April 30, 2021, both Louisiana and Texas have continued to reduce the limitations on how businesses must operate. First Guaranty continues to keep its locations open with certain modifications to our business practices. First Guaranty places a high priority on ensuring the safety and health of its customers and employees, including social distancing protocols and enhanced cleaning measures as part of its operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles. The consolidated financial statements and the footnotes of First Guaranty Bancshares, Inc. ("First Guaranty") thereto should be read in conjunction with the audited consolidated financial statements and note disclosures for First Guaranty previously filed with the Securities and Exchange Commission in First Guaranty's Annual Report on Form 10-K for the year ended December 31, 2020. The consolidated financial statements include the accounts of First Guaranty Bancshares, Inc. and its wholly owned subsidiary First Guaranty Bank (the "Bank"). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of the consolidated financial statements. Those adjustments are of a normal recurring nature. The results of operations at March 31, 2021 and for the three month periods ended March 31, 2021 and 2020 are not necessarily indicative of the results expected for the full year or any other interim period. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, and the valuation of investment securities.
Recent Accounting Pronouncements	Recent Accounting PronouncementsIn June 2016, the FASB issued ASU 2016-13, "Financial Instruments- Credit Losses: Measurement of Credit Losses on Financial Instruments". This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. The ASU amendments require the measurement of all expected credit losses for financial assets held at the reporting date be based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires assets held at cost basis to reflect the company's current estimate of all expected credit losses. For available for sale debt securities, credit losses should be presented as an allowance rather than as a write-down. In addition, this ASU amends the accounting for purchased financial assets with credit deterioration. On October 16, 2019, the FASB approved an effective date delay applicable to smaller reporting companies until fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. First Guaranty is a smaller reporting company and has delayed the adoption of ASU 2016-13.

Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds or credit risks) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy. Securities available for sale. Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Securities classified within Level 3 in First Guaranty's portfolio as of March 31, 2021 includes corporate debt and municipal securities. Impaired loans. Loans are measured for impairment using the methods permitted by ASC Topic 310. Fair value of impaired loans is measured by either the fair value of the collateral if the loan is collateral dependent (Level 2 or Level 3), or the present value of expected future cash flows, discounted at the loan's effective interest rate (Level 3). Fair value of the collateral is determined by appraisals or by independent valuation. Other real estate owned. Properties are recorded at the balance of the loan or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Fair values of other real estate owned ("OREO") are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values or recent sales activity for similar assets in the property's market; thus OREO measured at fair value would be classified within either Level 2 or Level 3 of the hierarchy. Certain non-financial assets and non-financial liabilities are measured at fair value on a non-recurring basis including assets and liabilities related to reporting units measured at fair value in the testing of goodwill impairment, as well as intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. The following table summarizes financial assets measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: (in thousands) March 31, 2021 December 31, 2020 Available for Sale Securities Fair Value Measurements Using: Level 1: Quoted Prices in Active Markets For Identical Assets $ 3,500 $ 3,000 Level 2: Significant Other Observable Inputs 47,700 209,359 Level 3: Significant Unobservable Inputs 16,492 26,189 Securities available for sale measured at fair value $ 67,692 $ 238,548 First Guaranty's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.

The change in Level 1 securities available for sale from December 31, 2020 to March 31, 2021 was due to a net increase in Treasury bills of $0.5 million. The change in Level 2 securities available for sale from December 31, 2020 to March 31, 2021 was due principally to transfer of $152.9 million in U.S. Government agency securities from the available for sale to the held to maturity portfolio. $0.8 million in corporate securities and $1.1 million in municipal securities were transferred from Level 3 to Level 2 from December 31, 2020 to March 31, 2021. There were no transfers between Level 1 and 2 securities available for sale from December 31, 2020 to March 31, 2021.
